I noticed your question while looking for information about the AMPCOIL. I do not own one. I am an RN and an ONDAMED practitioner and am looking at the coil to add to my collection of devices. I first had a zapper, ( Hulda Clark s) then the ultimate Zapper, now the ONDAMED. I spoke with another AmpCoil user yesterday and she told me she is having great success wth the device. I have had Lyme disease. no fun, and no longer thanks to my devices... By the time Lyme sufferers find ENERGY, they are broke and broken. These PEMF devices have made a huge difference for many people. Lyme spirochete hides, but it can't hide from frequencies (from what I understand). Everyone is different. it is difficult to tell how long it will take for the result you want but with perseverance, I believe ENERGY is a I"best option" for many. This device (from what I can tell speaking to other practitioners) is more targeted than say, a rife machine since figuring out what frequencies at best, can be tricky. Like I said...I don't (yet) have a coil but hope to. I"m impressed with the people that have them and the testimonials I have heard; I am mostly a "lurker" so you won't find many comments from me. if that makes me suspect , whatever. I have nothing to gain by saying positive things about PEMF devices. They have helped me and my family (dogs) greatly. hope this helps. This is not intended to be medical advice. I hope you can find relief. My best guess is that you are on the right track, looking at the coil.
